Drive past the anthurium, take a left at the second traffic light.
Rather, forget about it. The plant that Ben mentions in his instructions to John does not seem to have any significance as far as I can tell. Anthuriums are a just popular commercial greenhouse tropical plant, valued for their unique flowers and the colorfully variegated waxy foliage. They were very popular in the post WWII Pacific-theater years and often the subject of fabric design, especially the heavy bark-cloth used for upholstery and curtains. I have not found any reference linking them to any type of science or alchemy.
Its name is Greek for "tail flower". I found two Victorian meanings in anthurium-giving; either hospitality or intense attraction, neither one of which seems to have any underlying purpose to LOST mythology (accept maybe the latter since we might get our Orchid station physics lessons in this cluster-finale). Oh well, sometimes a flower is just a flower, right Doctor Freud? At any rate, I'll be buying myself one this weekend just for the heck of it, most likely. :-)
